Of course, you could try talking to your parents but I have a feeling they won't be open to listening. They didn't like him before and this is not going to help, given their apparent stance on his sexual orientation. Your fiance also shouldn't feel obligated to explain or defend such a deeply personal part of himself, but I am curious, what are his thoughts on your parents' knowing this?
Your parents might kick and scream, but you are the one marrying him. You obviously accept him as he is, which is the most important factor here. It would obviously be great to have your mom and dad's full support, but you might find yourself needing to proceed with the wedding without their approval. Do you feel you can do so?
